Title: A level regulating and/or vibration dampening device for a snow-removing machine
Inventor: YAMAMOTO TAKAHIRO
IPC: F16F9/02
Filed: 2000-07-06
Abstract: In a snow-removing machine, an expandable and contractible regulating mechanism is coupled between a steering handlebar of a machine body including a snow-removing section and a drive section capable of being turned relative to the machine body about a wheel driving shaft, and is capable of regulating the level of the snow-removing section relative to the drive section. The expandable and contractible regulating mechanism is comprised of a cylinder connected to the machine body, a piston which divides the inside of the cylinder into a first chamber and a second chamber, a piston rod coupled to the piston and connected to the drive section, a communication passage permitting communication between the first and second chambers, and an on-off valve for opening and closing the communication passage. A high-pressure gas is filled in the first and second chambers, so that the expansion and compression of the high-pressure gas is permitted upon closing of the on-off valve. Thus, during a snow-removing operation of the snow-removing machine, vibration applied to the drive section can be absorbed utilizing the expandable and contractible regulating mechanism for regulating the level of the snow-removing section.

IPC: H04B7/26
Filed: 2000-11-02
Abstract: A method utilizing statistical interpolation techniques to analyze and simulate the spatial variability and continuity of radio frequency data collected from a wireless cellular system. The method is used for cellular system planning and management. After installation and setup of cellular base stations, further analysis and refinement of RF data is implemented to determine signal coverage of the tower, locations of RF holes in system, reuse of frequencies, and overlapping RF signals between two or more towers causing interference. The method analyzes raw RF power data that is collected by drive testing a sample of roads in a cellular system. A geostatistical model of the RF propagation at a cellular system is determined through kriging. The RF path loss trend estimation is extracted from each the raw data and modeled to describe data variability across the entire cellular system area. An estimated path loss signal map is then prepared for any area of interest within a cellular system.

Title: Wireless systems combining arrangement and method thereof
Inventor: UPADHYAYULA L CHAINULU
IPC: C05G3/70
Filed: 2000-12-07
Abstract: A system and method effectively combines communications of the base stations of multiple wireless systems on the same antenna structure. In one implementation, a wireless system combiner serves as an interface between base stations of first and second wireless systems ("first base station" and "second base station") and a shared antenna to substantially eliminate spurious noise from the first base station at frequencies allocated to the second base station and prevent transmit power from the first base station from feeding into the reception circuitry of the second base station in a shared antenna configuration. The combiner includes a first combiner filter between a duplexer of the first base station and a common connection point and a second combiner filter between a duplexer of the second base station and the common connection point. The first combiner filter filters out spurious noise generated by first base station transmitter at frequencies outside the frequency band allocated to the first base station, for example using a high Q value band-pass or band-reject filter. The second combiner filters out signal power at frequencies outside the second base station receive band to prevent transmit signal power of the first base station from feeding into the second base station's receiver circuitry, thereby preventing intermodulation.

Title: Method and system for generating messages including a verifiable assertion that a variable is within predetermined limits
Inventor: CORDERY ROBERT A
IPC: H04L9/32
Filed: 2000-12-08
Abstract: A method and system for generating messages from which it can be verified that a variable does not exceed a predetermined limit. The message can be a postal indicium. A message originator, which can be a postage metering system, receives a message in the form R-K(T), where R is a trapdoor function, K is an integer equal to the limit, and T is a plain text, from a data processing center which maintains the inverse function R-1 in secrecy. The message originator computes S m =   R m(R-K(T), where m is a current value of the variable, and incorporates S m into the message. A verifier verifies that m < K by confirming that R K-m(S m) = T. The verifier cannot compute R K-m(S m) for m < K since it does not have R-1.     For the same reason the originator cannot compute R-K'(T), k' > K, from R-K(T).

Title: Traitement d'aliments par ondes de choc continues avec reflexion de ces ondes
Inventor: LONG JOHN B
IPC: A23L13/00
Filed: 1999-07-02
Abstract: De l'eau et des morceaux de viande (P) sont pompés dans une canalisation (100) dont les parois sont en plastique et qui présentent une impédance acoustique proche de celle de l'eau. La canalisation est immergée dans une cuve (400) remplie d'eau. Un générateur d'ondes de choc (200) (électrodes de décharge de condensateur ou explosif chimique) crée une onde de choc dans l'eau. Cette onde de choc traverse la canalisation sans réflexion sensible car l'impédance de la paroi de la canalisation correspond à l'impédance de l'eau. L'onde de choc assure l'attendrissage de la viande et sa stérilisation partielle au moins. Un cylindre résistant de réflexion des chocs réfléchit les parties de l'impulsion de choc sur la canalisation. Des explosions continuelles sont répétées assez rapidement pour assurer l'attendrissage de la viande. Par ailleurs, il est possible également de placer la viande dans de l'eau dans un conteneur fermé à la place de la canalisation.

Abstract: Selon cette invention, dans un processus de préparation d'une bière faite à partir d'une céréale ou d'un mélange de céréales, on prépare une suspension aqueuse de céréales à partir de céréales extraites par voie humide, réduites en flocons ou écrasées, de farine de céréale thermiquement traitée et de leurs mélanges. La suspension est maltée à une température supérieure 50  DEG C en présence d'enzymes amylolytiques et éventuellement d'enzymes décomposant les protéines. On empêche la décomposition de  beta -glucane soluble en régulant l'activité de  beta -glucanase. Après refroidissement, la substance insoluble est retirée pour donner un malt de céréale qui est bouilli avec des houblons pour mettre fin à toute activité de  beta -glucanase. Pendant le processus, on peut ajouter des quantités sensibles de moût traditionnel bouilli. La fermentation du moût permet d'obtenir une bière contenant une quantité élevée de  beta -glucan soluble. L'invention concerne aussi des produits préparés au moyen du procédé de l'invention.

IPC: F25B41/00
Filed: 2001-06-04
Abstract: A refrigerant dispensing tool includes a three section body with a top manifold section having an evacuation port, a refrigerant supply port and an oil supply port. The intermediate body section has three elongated and converging valve chambers which connect with the corresponding ports and receive corresponding elongated fluid pressure balancing valve members. The valve members are independently operated and precisely controlled by corresponding air actuated pistons which receive pressurized air from corresponding air ports within the manifold section. An air actuated and spring biased annular piston is supported between the intermediate and base sections of the body and operates a set of circumferentially spaced balls which releasably clamp the tool to a stem valve fitting for a refrigerant system. An air actuated pin extends on the center axis of the body for opening and closing the valve stem within the fitting, and a resilient sealing ring forms a fluid-tight seal between the base section and the fitting.
